"...this is the only publication devoted wholly to one of the most vital concepts in the art of animated film... The book is a vital source of reference for students as well as every studio and every animator...It's also easy to keep around for reference, it's not a huge coffee-table bible sized book made to impress. It just gives the facts, numbers and formulas and a few drawings to illustrate. Made by animators for animators.Although it was principally written for 2D animation, this book has crucial information for any animator (2D, CGI or model animation). It explains simply and clearly how to time a walk or a run; how to give your character a sense of weight; how is transmitted; the effects of friction; spacing -and much more. The new foreword by John Lasseter puts these traditional skills in today's context, and gives praise where it is due. Every animator, would-be animator, animation studio and animation course should have this book."
